Repairing a Dead Logitech Speaker System (Z313 FIX LOG)
Вставка
- Опубліковано 25 сер 2024
- I've just bought this speaker system and it went broken. I won't blame Logitech for this though, it seems like the cable is damaged and I broke the STBY thing while I tried to repair it. But I would love it if Logitech upgrades their product quality.
The very first you should do when fixing something like this is to check the connections; is the mains wire connected right? Is this wire connected to the other end? If the answers are "no", maybe that's where your thing is broken. Fix it, either buy a new cable or just fix the connection using your ways.
If none of them were broken, then you might want to start opening things, check the datasheet then test things to see if there's something strange. See if there's a broken component (maybe roasted, or something like that) and try to fix things.
There's a National Examination for junior high coming, so I'm sorry that I can't do much, schedules are tight and I'm trying my best to come out with topics and make videos. As always, have a good day.
i was gonna watch this but forgot my speakers are broken...
LMAO X2
same here LOL

Thank you very much for putting your skills and time into the troubleshooting for this speaker. Mine arrived fresh out of the box with the STNDBY issue. I actually think it may be due to hap hazard circuitry work. Either way, with my minimal electronics background I was able to apply your first fix, and my speakers now work flawlessly!! Thanks again :D
Guys i fixed logitech z313 speakers by watching this video. Thanks man i really appreciate. The only thing i wasn't able to do is when i connect 5v IN, is to get wired remote control work (on/off). So i was playing around and found a solution. I've solder a wire from main board IN to remote on STBY IN(if it's called like that i forgot :D) and after that i had a full control meaning i can turn on/off speakers, volume is working and everything else is working fine now. I just posted this bcs maybe i can also help someone. Thanks man for instructions again ;) Cheers!
Or just join IN and OUT on the main PCB.
I did that on mine and it solved the issue somewhat (it keeps the speakers always on though)
Hi,can you help me? i have a logitech z323 ,and i broke the volume controller,how to use it without it ?
Is there a way to get this audio without the music? It drowns out your voice. Looks very helpful, tho.
bro i have the same speaker problem the power light up but no sound
So the only problem I have with my speakers, are that the R speaker is way quieter. I did a little trouble shooting on my own, I balanced all the way to the Right and the sound was still very very low. It plays at full power out of the Left. Same model as the ones shown in the video, if you have any suggestions on how to fix I would love to hear them
I am your 1000th subscriber! Congratultions!
Thank you very much, first of all. I fixed the device with the video. I've changed Integrated extra. I'm using it without any problems right now.
Mine won't turn on. I only need to buy LM7805?
I had a similar issue that I just resolved, where the cable that connects the input/volume knob to the board had really deteriorated, and no signal was coming through the activation wire. Ran some 22ga black wire in parallel from controller to amp/sub and now the connection is solid, speakers are back to working.
Wonder which wire will deteriorate next...darn throwaway culture items
yeah same issue for me, but I simply shortened the cable and soldered it inside the control thing, now it's dead again so I'm going to try to salvage some other jack cable I find
Ok I know this is old, bit is there a way for you to solder two wires together so that without the speakers, the sub stays on?
That’s what’s wrong with my Logitech z3
The speakers plug into the sub just dont connect the speakers to the sub duh!!
this is complicated.... for someone who doesnt have electronics background
It's actually just adding a 5V to interrupt the system.
Still complicated... and what if you cant afford any soldering equipment?
PINEWOOD℠ REPORTER I guess you could just dump your broken speaker and buy a new one.. I mean, it's *cheaper* that way than repairing the broken speakers, right..?
@@ArsyadKamili You got me curious. I have a Logitech X210 that won't power on and maybe this is the problem? I can hear the transformer working but other than that nothing.
I have z213 subwoofer is dead but speakers it is fine, how to repair?
Hola amigo a esta placa se le puede poner 16 vol gracias
after 2 years, this speaker finally gave out
after 2 days it gave out
Finally? That’s rubbish!
That's the same thing that happened to mine working great when I turned them off tried to turn them on the next day I get no sound
A Z323 subwoofer without the stereo speakers suddenly stopped working. Could it somehow unstably triggered headphone mute despite no poti connected to the db-9 socket?
i had the same speaker and same problem 4 years ago. instead of fixing it i just bought another speaker
What's the funeral music for?
this is my 2nd and the last purchase for Logitech speaker. the build quality is very bad.
Hi man. I got one edifier speaker. One button written" input" switch button that switch between USB, AUX and FM is not functioning. It cant switch. What is the problem actually.
May you tell me how did you connect the middle prong on the Im7805 ?
I have a Z333 and the subwoofer stopped working yesterday, but the speaker are still working. Any ideea on how should I approach this?
Thanks Kamili for this awesome video. I have the exact problem with my Z313. My input cable which leads to the volume and power control was working only after twisting the cable. Eventually yesterday there was a wrong contact inside the cable and part of it burned and smoked. I then had to unplug the power cable quickly. I tried to fix it by restoring the cable, i cut the section that was burnt and joint the cable. The led could now turn on when i press on the on button, but the input signal seemed not be received. Since this job needs more electronics background, and because the fault is similar to yours can i just change the STA540 microchip? I really needs yr help/input
Same question here. thanks.
Was the green light next to the on/off button still working before you fixed the speaker set?
Great tutorial by the way :-) very insightful!
Does anyone knows how to get schama of this power supply? Thanks in advance for giving it to me ^^
I’ve got the same product and same fault, sayangnya ga ngerti elektro spt kamu mas. Keep up the channel 👍
So is the lm7805 necessary
i need help i connected 110v to 240v socket and i think it blew the fuse. how do i change it
mine is grounded or gets hummm..
Hello I know this is old but any help would be much-appreciated my speakers, work fine and everything is great except that the power/volume control oval thing? only seems to want to turn on 1 IN 100 clicks haha any reasons why? not looking for a solution just where is the problems at? Loose connection?
One day the speakers were working normally and the day they opened the computer they did not work. I disconnected the 2 speaker cable from the base and I disconnected the base cable from the computer hunt. I then connected the 2-speaker cable directly to the computer hunt and just make very little sound. Can you please help me with my problem?
Hi! I got one z313 brand new. I'd like to ask you if is there a way to switch it from 110v to 220v. I would like to use it without an external AC converter. Thanks in advance for any help.
Well, there is a way. You can find a 12v power supply that has 110v ac input and replace the power supply that's in the subwoofer with it.
The new power supply needs to have the same capabilities as the old one, you'll need a power supply that can supply at least 3A.
There isn't a simple 'switch' though.
Arsyad Kamili couple minutes after see your video and leave you the question I opened it removing the speaker and found this power supply. But also I noticed that has a board with a fuse and others few components. I knew that it should have this PS so I was wondering myself if this PS would has two input wires, one for 110v and other for 220v, like others similar models. Unfortunately not. I can do tasks with the soldering iron but I'm dummy in electronic components, so I don't know which fuse and other components (except the PS) I have to replace. Anyway, thanks for your reply!!
It was good to know the subwoofer port had 4 screws before I pulled mine out...
had mine for like 12 years and theyre finally shitting out.
seems to be the connection at the remote, as it still works if i force it upside down. gonna see what i can do but theres like 6 wires crammed in the little rubber neck thing.. might not be worth the effort lol i hate small wires
Hi Arsyad, my speaker had the same problem as yours not turning on and its the same model as well, I did what you suggested connecting a 5v power supply directly to the board and it worked, so the question is, when you did the step before applying the LM7805 fix, I did the same by connecting where you soldered the white wire (JP23) to the stby and it does not work... did you connect anything else? or I have to get myself a LM7805 for this to work??
Wait, so you've fixed the problem? The first fix was failed for me, so I did an alternative with the LM7805 method. If the speaker's already good, then I don't think you'll need to do anything else.
Er it only worked when i attached an external 5v power source to it... but the first fix you said you thought it did not work because you did not attached the speakers...
My Logitech speakers are now not working at all. One day completely fine, next day nothing at all. I know nothing about the chip board and components, and after 5 hours of researching UA-cam and going to my local fix it dude, I was told just for him to take a look would cost me more then they are worth, so I just went and spent $800 on Yamaha studio monitors, and I think I'm going to sadly have to throw my logitec speakers in the bin. I did have them for 5 years and after my band broke up I got a further 4 good guitar cover videos out of them, so I got my $89 worth. Spewin it come to that, cos Logitech speakers are sweet. I had the z323 model. Cool video for ppl that are smart in that area though. Me unfortunately not. I came here for one last chance to revive my legendary speakers, afraid it's just not a simple fix. I guess it's R.I.P Logitech speakers for me
Studio monitors are a little overboard for general listening. Unless you're going to be editing and producing audio, you might be better off with speakers that are made to sound rich and vibrant rather than sound flat and accurate.
in teh case of this shitty system the power supply fails frequently.You can use any 12V4Ah supply insdtead of provided one
Bhai mara logiteach Ka 2 speaker ma sa 1 speaker not work
Issue I’m having with my z313 system is that my right speaker plays at a low volume, and even though the speakers labeled Left and Right, both channels are played on each speaker so it seems. If I go into my computer setting and try to lower the left channel volume nothing occurs, only adjusting the right channel will silence both speakers. I noticed that if I have the 3.5mm cable loosely plugged into the amplifier the right speaker will play at a balanced volume to that of the left speaker; but if I plug the 3.5mm cable fully into amplifier right speaker volume is reduced to very low.. Any idea what the issue could be?
I have the same problem, bro. right speaker is very low conected to the subwoofer.
Did you repair it?
@@RiddzenRock nah threw the speakers in the trash lol, reminds me that I need to toss the woofer too, just was too lazy at the time. Probably better to just invest in some other system. I just use my astros or ear buds these days.
@@OneStopShopGarage Sure, bro. I'm going to do the same :(
Can you share the diagram with us? Thanks
My right Channel went out on these speakers so I just bypass the circuit board all together. I'm talking about the control pad circuit board not the one in the subwoofer just to clarify.
Can you tell me how you did this?
thank you for the tutorial, but something is not right with your thumb finger!
Hi! May be you could help me with the problem of my Logitech LS11 speaker. The problem is the sound is so weak even if the volume is maximum, and there's a noise in it like a broken glass, before it was so clear and loud. May be you know how to fix such problem, which I coul do to my speaker. Thanks...
Try to look inside, and test visible connections with your multimeter, test the power stuff, check the output to the speaker (it'd be good if you have an oscilloscope), and see if something is wrong. If something is wrong, try to find a way out. It should be easy if you know the problem.
If you don't seem to see anything wrong, learn the circuit. There's should be a main amplifier chip located in the circuit board, look at the name or number, google it, then learn the datasheet and how the circuit behaves.
Now, if you look at the datasheet properly, you should get a slight understanding in what's wrong, test your hypothesis. If right, fix it. If wrong, try another hypothesis.
p.s.
If you're tracing copper traces with your multimeter, draw the result on a paper to make things easier.
I only have multi tester. Im currently onboard a ship.
Thanks for this rundown Arsyad -- having the STA540 data sheet is very helpful! So I can avoid removing the PCB from my subwoofer cabinet, do you happen to remember the supply voltage to pins 3 and 13 of the STA540? I'm considering replacing the woofer and I'm trying estimate the power reduction from going from the stock 4 ohm unit to a better quality 8 ohm speaker and figuring out if any resulting volume and/or headroom reduction would be made up by the difference in woofer efficiency. I'm using active JBL satellites, so I can balance highs and lows without worrying about matching the satellites to the sub.
Hi Arsyad, I have Logitech z333 its smps blown can I put a new SMPS ? Its writen 94v-0 E317641 ZR-01 I want to know IS ITS 94VOLT psu OR 12 VOLT ?
I don't think it's 12V because it's a 80 Watts system. But I can't be sure that it's 94V either because 94V is not a standard voltage number. You'll need to check what's the amplifier chip and maybe find somethinf in the datasheet, or analyze the SMPS to see what voltage it might have.
Standard voltages are 12, 24, 48. If you manage to know what voltage the SMPS is, you can put a new one.
Mine works completely fine, all except for the sound I can’t hear anything 🤦🏾♂️
thank you. broooo
i have logitech z333 when i try to turn it on nothing happens but when i plug in other wall plug it works for like 2 days and thrn same problem again how to fix that ?
If it trips the breaker, then it might be a grounding issue.
@@myhops the plug is very likely not grounded
My amplifir had a smush part
i googled how to fix a computer speaker and you have the same exact speaker im trying to fix. honestly i will stop buying logitech products, as pretty much everything they sell breaks in a few years.
I honestly expect them to last for just 3-5 years. I think that's what I expected I have with that range of price. Logitech is not the kind of brand you expect to work properly after 15 years. I think they fulfill my expectations and therefore I'm gonna stick to buying their products until I have the ability to buy products with higher prices :)
I bought an edifier xm2pf 2.1, it stopped working and don't turn on i was using it for less than 2 years, it's not ok what the industry of speaker does.
it works thx!!
Anybody here could give me an advice because I badly need it. The rat came and chewed and chopped the wires of my Logitech Z313,
I just wonder if there are still hope for this. The speakers are good. Just the wires are being massacred. Please help me.
my friend, is LM7805 or L7805CV?
Both work well for this application.
Hi! excuse me I don't speak english so well, so i hope you can understand me.
How are you supposed to fix that, I put 5 volts external and it works, but I got lost with the regulator, can I fix it without it? Or is it necessary to use the component? If so, could you send me the diagram to solve it?
A regulator is the best solution, and it's not that hard to get.
But if you can't find a regulator you can try this method: use your multimeter set on to measure voltage, put the negative probe to the negative part of the circuit, and start testing with another probe, touch every pin you see on the circuit and see if you can find something more than 4.5V but below 7V.
I don't have the schematic, but I think there's should be a voltage of about 6.25V close to two black SMD IC (I show this in the video). Solder that 6.25V with a wire, connect and solder it to the STBY pin in the main circuit board (STBY pin should be one of the pin that's connected straight to the control pad.)
Good luck.
Look at 04:06, that should be where the 6.25V is, or somewhere close.
Perfect thank you very much for the answer, I'll try with a cable to the STBY pin and I'll tell you how it was
It is ready, no longer fails at any time. Thank you very much for the video and the answers.
Glad it worked!
could you please post the website to the board manual?
There is no board manual as far as I can remember.
alright thank you and what is the site/program you are using time 1:36
Oh, that. That's the schematic of the amplifier IC. You can download yours here:
www.st.com/resource/en/datasheet/sta540.pdf
It's filled with all the details of the IC you might need to troubleshoot it or maybe build your own board.
Thank you very much.
You're welcome.
Geez. You are brilliant but I can not understand half of what you are saying.
I am an Electrician so I understand some of what you are doing. It’s just that, I am a Southern man in Florida. My bad.
hey friend,
how to i check that 15leg IC to use digital meter bcoz my HT same like yours nd its on bt no sound come in it.... so plz you tell me what i do...
Check the datasheet, you should be able to see what each pin does, what works and what doesn't.
I can't hear anything.
Replay and increase volume. you maybe deaf.
i cant fucking hear
i bought my logitech z313 brand new and my two main speakers were ridicously quiet and even installing an APO equalizer boosting them by 11.4db still didnt help enough but instead of the speakers sounding like my headphones at 1% they now sound like my headphones at 6%!!!!!! fuck me for buying t his crap now i have to ask dad for help because i dont have the experince neither the equipment of soldering
Hello Sir, I want to remove the remote controller from this sound system, but how to remove It ?
You can bypass the controller system by connecting the audio cable that goes to the control pad to go straight to the amplifier input.
But you should remember that the amplifier needs a 5V voltage to the enable pin to turn it on.
@@ArsyadKamili how to give the pin 5v ?
@@ArsyadKamili I've noticed that the controller has A/D converter IC, so what happens if I bypass the controller. Thanks!
Music is verry annoying as you are speaking very quiet
Learn how to talk clearly man.It's like you are talking Urdu or something.

Logitech speakers are pieces of shits. I can't even get the screws out to take it apart,
Logitech sucks raw ass. Don't even bother getting them. They have reputation for the wires soldered inside the speakers to come undone. Easy enough to just solder it back right? ...NOT WHEN YOU CAN'T GET THE DAMNED SCREWS OUT OF THE HOUSEING. And why do they have 6 screws?
That music thoughh
Fuck ion even know shit about this. Heeeelp
Cant understand you well at all and that music pretty much ruined the video bro......thanx alot
